You are waiting for DNS I assure you, it can take 12-24 hours. This is not a dreamhost thing it's how DNS is designed to work. I just checked again and it hasn't reached me yet either.
It's really probably a little sooner than I normally would use this, and it may not help at this point, but go to manage domains in the panel, find that domain and click the DNS link right under the domain name. On the next page you will find a button to force a refresh, go ahead and do it.
